2. Description of the Related Art The sanitary napkin disclosed in Japanese Patent Publication No. 6-502336 has wings on both side edges, and comprises a liquid-permeable upper sheet, a liquid-impermeable back sheet,
It has an absorber core and a liquid-permeable separating structure. The spacing structure moves the upper sheet away from the absorbent core to improve contact with the wearer's body.When the napkin is compressed by the wearer's thigh, the spacing structure has been made relatively flat. At least a part of the upper portion is deformed so as to be convex upward.

In the known napkin, a wing is folded on the underside of a crotch region of shorts,
It is secured to the underside of the crotch area using the adhesive area of the wing. In such a napkin, the side edges are fixed, and only when the side edges are compressed by the wearer's thigh, the separating structure becomes convex upward. In such a napkin, when the shorts worn tend to drop and the compressive force of the thigh does not easily act, the separation structure does not become convex, so that a good contact state between the upper sheet and the body cannot be obtained.

FIG. 4 is a cross-sectional view of the napkin 1 taken along the center line II-II. The napkin 1 is fastened to the shorts 22 shown by a phantom line.
The elastic member 13 is in a contracted state. When the elastic member 13 in the extended state in FIG. 2 contracts as shown in FIG.
The deforming means 7 deforms so that the upper sheet 11 becomes convex upward, and deforms so that the lower sheet 12 becomes convex downward, thereby exhibiting an annular shape. With the deformation of the upper part 11, the core 4 is deformed so that the gap between the compressed grooves 8 and 8 becomes convex upward, and adheres well around the vaginal opening of the napkin wearer through the topsheet 2. I do. When body pressure is applied to the illustrated napkin 1 from above, the elastic member 13
Extend to make the napkin 1 flat as shown in FIG. Since the deformation means 7 is fixed to the shorts 22 only near the center line III-III, the elastic member 13 is not hindered from expanding and contracting by the shorts 22.

FIG. 6 is a view similar to FIG. 4 showing an example of the embodiment of the present invention. However, in this sanitary napkin 1, a deforming means 7 different from that in FIG. 4 is employed, and the napkin main body 6 is not provided with the compressed groove 8. The deformation means 7 is made of an elastic sheet material such as rubber or elastomer, and is a member 26 having a ring-shaped cross section in the width direction of the napkin 1. This member 26 has a center line III-III
Extends along the longitudinal direction of the napkin 1 and is joined to the lower surface of the back sheet 3 at and near the center line III-III via an adhesive 17, and the radially opposite side of the joined portion Is coated and protected by a release paper 21. When body pressure is applied to the napkin 1 from above, the annular member 26 is pressed and elastically deforms into a flat one as shown by the imaginary line.

FIG. 7 is a drawing showing an example of the mode of use of the napkin 1 of FIG. The napkin 1 shown in the sectional view is
The second napkin 30 is located at the center in the width direction of the second napkin 30 which is separate and wide. The second napkin 30 includes a liquid-permeable top sheet 32, a liquid-impermeable back sheet 33, and a liquid-absorbent core 34 interposed between the sheets 32, 33. It is joined to the upper surface of the topsheet 32 through the intermediary. In order for the core 4 to follow the movement of the deformation means 7 with the napkin 1, the core 4 must be made relatively thin. At this time, if there is a problem that the core 4 is thin and the amount of body fluid absorbed is small, the problem is solved by using the napkin 1 as shown in the figure, and at the same time, around the vaginal opening of the napkin 1. It is possible to improve the adhesion to the substrate.

The present invention can be implemented by replacing the plurality of elastic members 13 with one elastic member 13. Also,
The elastic member 13 may be a single elastic sheet having the same size as the upper and lower sheets 11 and 12. The compressed groove 8 is
In addition to serving as a starting point when the napkin 1 rises, it is also useful to prevent menstrual blood from leaking by flowing menstrual blood flowing laterally along the topsheet 2. The groove 8 can be replaced with a straight one instead of a curved one as in the illustrated example. In addition, the present invention can be implemented without the groove 8.
